How Can I Control Roots In My Pipes?

Tree roots may be out of sight, but they can quickly become a major plumbing problem. If you’re experiencing slow drains, gurgling toilets, or recurring backups, roots might be invading your sewer line.

In this blog, we’ll explain why roots grow into pipes, how to detect the problem early, and what solutions are available to keep your plumbing system clear and flowing, especially for homeowners in Phoenix, AZ, where large trees are common in older neighborhoods.

Why Do Roots Grow Into Pipes?

Tree roots naturally seek out moisture, nutrients, and oxygen. Sewer pipes, especially older clay or concrete lines, often develop small cracks or loose joints that allow water to leak into the surrounding soil.

Roots detect this moisture and grow toward the source, slipping into even the smallest pipe openings. Once inside, they expand and form a web that traps debris, including toilet paper, grease, and waste, causing major blockages.

Signs That Roots Are in Your Pipes

Look out for these common warning signs:

• Slow-draining sinks, tubs, or toilets

• Gurgling sounds in your drains

• Frequent backups, even after snaking the line

• Sewage smells in your yard or home

• Unusually lush or green patches in your lawn

If you notice any of these, it’s time to schedule a sewer line inspection.

5 Effective Ways to Control Tree Roots in Pipes

1. Schedule a Camera Inspection

A professional plumber can inspect your sewer line using a video camera to identify root intrusion and the severity of the damage.

2. Hydro Jetting or Mechanical Root Cutting

• Hydro jetting uses high-pressure water to blast away roots and debris.

• Root cutting tools can mechanically remove thick root masses from the pipe interior.

These solutions are fast and effective—but may only be temporary if the pipe isn’t repaired.

3. Apply Root-Killing Chemicals

Copper sulfate or foaming root killers can kill existing roots and help prevent regrowth. These are best used after clearing the line for longer-term maintenance.

Note: Only use root-killing treatments approved by your local plumbing professional to avoid damaging your pipes or the environment.

4. Pipe Lining or Trenchless Repair

For a long-term solution, you can reline the damaged pipe from the inside using a cured-in-place pipe (CIPP). This seals cracks and joints where roots enter, without digging up your yard.

5. Replace Severely Damaged Sewer Lines

If the damage is too extensive, full sewer line replacement may be necessary. Modern materials like PVC are root-resistant and far more durable than older clay or cast iron pipes.

Preventing Future Root Intrusion

• Avoid planting trees near your sewer line

• Choose slow-growing trees with small root systems

• Schedule regular plumbing inspections

• Use root barriers during landscaping projects

• Flush root-killing treatments annually (as recommended)

Controlling roots in your pipes requires a combination of early detection, the right treatment, and preventive maintenance. Whether you’re dealing with frequent backups or just want peace of mind, our experienced plumbing team is here to help.
